Doug,
Thanks for the reply. Immediately after hitting send I found exactly
what I was looking for. Don't know why I didn't consider doing a 'man
sox' earlier. I must be getting senile. ;)
That said, I altered my initial .gsm files and made them 75% quieter (-v
.25). I replaced my loud files with my newer, quieter files and
reloaded res_musiconhold.so to no avail. I confirmed the new files
*are* quieter, but Asterisk still plays them extremely loud. Do I need
to reload a different module, or perhaps completely restart Asterisk to
use these newer files?
Thanks,
Jay

Hi folks!
I did notice that sox has a -v flag for adjusting volume, but danged
if I can find documentation online that'll tell me what parameter to
pass.
Doing a 'man sox' does wonders:
-v volume Change amplitude (floating point); less than 1.0 decreases,
greater than 1.0 increases. May use a negative
number to
invert the phase of the audio data. It is
interesting to
note that we perceive volume logarithmically but this
adjusts
the amplitude linearly.
So, this is how I increase the volume on my paging
sox paging.gsm -v 4 /var/lib/asterisk/sounds/outx2.gsm
